DANGER!

Electric shock

The connection of two or more modules in series results in the accumulation of
voltage and impose s danger. Do not inser t electrically conduc tive parts into con­nectors! Do not attach solar modules and wiring with wet connec tors! Make
sure to work with dry tools and under dry working conditions!

Work on live parts

When working on wiring, use and wear protective equipment (insulated tools,
insulated gloves, etc.)!

WARNING!

Arcing

Modules generate direct current (DC) when exposed to light. When breaking a
closed circuit, a dangerous arc may be generated. Do not cut any live wires.

Safe installation

Do not carry out installation work in strong winds. Secure yourself and other
persons against falling. Secure work materials against dropping. Ensure a safe
working environment so as to prevent accidents.

Fire protection/explosion protection

Modules must not be installed in the vicinity of highly flammable gases, vapors
or dusts (e.g. filling stations, gas tanks, paint spraying equipment). The safety
instructions for other system components must also be followed. Make sure to
comply with loc al standards, building regulations and accident prevention re gu­lations during installation. For roof installation, modules must be mounted on a
fire-resistant roof covering rated for the application.

ATTENTION

Do not use damaged modules. Do not dismantle modules Do not remove any
parts or nameplates fitted by the manuf acturer. Do not apply paint or adhesives
to the module, nor work on it with sharp objects.

Unpacking and intermediate storage

Follow the Unpacking and Handling Instructions for alternative vertical long side
packaging solution.
Do not use the junction box as a handle. Do not place modules roughly on hard floor
or on their corners. Do not place modules on top of each other. Do not step or stand
on modules. Do not place any objects on modules. Store modules in a dry place.

Grounding of module and frame

We recommend ensuring the functional grounding of the module metal frame. If
an exterior lightning protection system is already provided, the PV system has to be
integrated into the protection concept against direct lightning stroke. Local stan­dards shall be observed.

Grounding in the US and Canada

The modules can be connected at the holes provided in the flange using a lay-in lug.
The lug must be a tin-coated copper lug, silver in color. Do NOT use a bare copper
lug, which is brown. A ny grounding method and components liste d according to NEC
requirements are also acceptable in the US and Canada.

General Information

This module is rated for us e in application class A acc ording to IEC 61730. For the elec­trical ratings please refer to the datasheet. Under normal conditions, a photovoltaic
module is likely to experience conditions that produce more current and/or voltage
than reported at standard test conditions. Accordingly, the values of ISC and VOC
marked on this module should be multiplied by a factor of 1,25 when determining
component voltage ratings, conuctor current ratings, fuse sizes, and size of controls
connected to the PV output.“

Underwriters Laboratories Information (U.S. and Canada)

The fire rating of this module is valid only when mounted in the manner specified
in the mechanical mounting instructions. The module is considered to be in comp­liance with UL 1703 only when the mo dule is mounted in the manner specified by the
mounting instruc tions below. A module with expose d conductive part s is considered
to be in compliance with UL 1703 only when it is electrically grounded in accordance
with the instructions presented below and the requirements of the National Electri­cal Code. Where common grounding hardware (nuts, bolts, star washers, spilt-ring
lock washers, flat washers and the like) is used to attach a listed grounding/bonding
device, the attachment must be made in conformance with the grounding device
manufacturer’s instructions. Common hardware items such as nuts, bolts, star was­hers, lock washers and the like have not been evaluated for electrical conductivity
or for use as grounding devices and should be used only for maintaining mechani­cal connections and holding electrical grounding devices in the proper position for

electric al conductivity. Such devices, where supplied with the module and evaluated
through the requirements in UL 1703, may be used for grounding connections in
accordance with the instructions provided with the module. The electrical charac­teristics are within ±10 percent of the indicated values of ISC, VOC, and Pmax under
standard test condi tions (irradiance of 100 mW/cm², AM 1.5 spe ctrum, and a cell tem­perature of 25°C (7 7°F)). Under normal conditions, a photovoltaic module is likely to
experience conditions that produce more current and/or voltage than reported at
standard test conditions. The requirements of the National Electrical Code (NEC) in
Article 690-8 shall be followed to address these increased outputs. To reduce the
operating temperature the module has to be mounted on any surface with a mini­mum distance of 4 inches (10 cm). In Canada the installation shall be in accordance
with CSA C22.1, Safety Standard for Electrical Installations, Canadian Elec trical Code,
Part 1.

Suitable ambient conditions

Artificially concentrated sunlight shall not be directed on the module or panel. The
module must neither be immersed in water nor be exposed to continuous wetting
(e.g. by fountains). Exposure to salt or sulfur (sulfur sources, volcanoes) implies a risk
of corrosion. The module must not be used for maritime (e.g. boats) or automoti­ve (vehicles) purposes. The module must not be exposed to extraordinary chemi­cal loads (e.g. emissions from manufacturing plants). If the modules are installed on
stables, a distance of 3.28 ft (1 m) to ventilation openings shall be ensured; apart
from this, the modules shall not be used as a direct roof panel on stables.

Appropriate installation situation

Make sure that the module meets the technical requirements of the overall system.
Other system components should not exert any adverse mechanical or electrical
influences on the module. Modules may bend under high loads. For this reason,
sharp-edged fixing elements or other sharp objec ts (e.g. cable ties on mounting sec­tions must not be mounted near the module back side. For modules connected in
series, only modules of the same amperage rating may be used together. For modu­les connected in parallel, modules with the same voltage ranges must be used tog­ether. The modules must not be operated at a higher voltage than the permissible
system voltage. The inside opening of the frame corner element is intended for
water drainage and must not be blocked. For system documentation, please note
the serial numbers.

Optimum installation

In order to avoid performance losses, all modules connected in series should be
arranged with the same orientation and tilt angle. The modules should be installed
in an all-season shadow-free area. Even partial shadowing results in yield losses
and is to be avoided. Ventilation of the module back side will prevent heat build-up
adversely aecting performance.

Mounting

The modules must be securely fixed at a minimum of 4 locations on the substruc­ture. Fixing is only allowed in designated areas. In regards to “Top-Down” mounting
methods, the maximum clamping pressure is 50 N/mm² (72.5 psi). Do not drill any
holes into the module. Use corrosion-proof fixing material.

Electrical connection

The modules are provided with factory-assembled cables and connectors . Do not
open the juncti on box in any case. Connectors may only be c onnected under dry con­ditions. Make sure to avoid gaps in a plug ged connection. Only singlec ore solar cables
with an adequate cross-section (4 mm² minimum) and appropriate connectors may
be used for connecting the modules. Cables should be attached to the installation
system by means of UV-resistant cable ties. Exposed cables should be protected
against sunlight and damage by suitable precautions (e.g. conduits) In order to limit
voltages released by indirect lightning shock, the area of all conductor loops must
be reduced to a minimum. Check that wiring is correct (polarity!) prior to starting
the generator.

Cleaning

In general, the modules do not need any cleaning if the tilt angle is sucient
(> 15°; self-cleaning by rain). In case of heavy soiling, we recommend cleaning the
modules with plenty of water (ap water or deionized water) without any cleaning
agents. If necessary, a soft cleaning device (sponge.g. sof t brush with split bristles)
maybe be used. In case of soiling by dust or sand the modules can be cleaned with a
soft brush without using water. Never scrape or rub o dirt; this may result in micro­scratches.

Maintenance

We recommend regular inspec tions of the system to ensure that:

1. All fixtures are securely tightened and corrosion-free;

2. Wiring is securely connected, properly arranged and free of corrosion;

3. Cables are free of damage;
Please also observe applicable standards.
